This is a step by step guide on how to make an Open Bionics Ada robotic hand. This is derived from the Dextrus robotic hand, by the Open Hand Project. It assumes you have either ordered the Ada robotic hand kit or have access to a 3D printer and are planning to print 3D parts from YouMagine or thingiverse. The list of required 3D printed parts, components and tools are stated below. If you have purchased the Ada kit, you can skip the first step and start straight from step 2.
This hand would provide an excellent research platform for robotics or a test platform for prosthetics research. It has been designed to be easy to build and repair and should be a great project for someone with interests in robotics or prosthetics and wants their very own robotic hand!
This instructable will take you through the assembly of the 3D printed parts, the mounting of the circuit board, and the uploading of test firmware. If you have all of the parts to hand, assembly should take around 1 hour. The assembly of this hand is exactly the same for both a left and right hand, the only difference being in Step 4, mounting the electronics.
- Printing and removing support material
- Inserting the motors
- PCB tray assembly
- Mounting the electronics
- Attaching the back cover
- Uploading the test firmware
- Attaching the finger tendons
- Hand is complete
- M3 Allen key
- Tweezers/Needle nose pliers
- Soldering iron (used for the push inserts)
- Micro USB cable
- 12V DC power supply
- Super glue
- 9 x M3 bolts (6mm length)
- 13 x M3 threaded push inserts
- 1m x 0.7mm tendon string
- 5 x Firgelli 12V linear actuators (PQ12-30-12-P)
- 1 x Open Bionics Almond electronics
- 5 x Micro gel fingertip grips
3D printed parts:
- PCB tray upper
- PCB tray lower
- Back cover
